This paper focuses on the use of real interactive simulations in order to improve student's knowledge, and to increase their autonomy for know-how acquisitions in engineering curricula. Simulations favor active manipulation but are not sufficient per se. Our simulations are integrated together with exercises and contextual information in a pedagogical canvas to constitute on-line accessible lessons. Those short lessons facilitate the implication of teachers for design and integration in their classrooms, and will allow future integration INTO data_ds.tmp_pub_more complete curricula, including distant project-based learning.
